World's First '3D-Printing Pen' Lets You Draw Designs in Thin Air

has allowed builders to take control of their projects with an astonishing degree of precision. For those who want a little more manual control and and a smaller price point, the 3Doodler by the folks at WobbleWorks is a great alternative. As the world’s first 3D-printing pen, the device takes the heated extrusion head of a normal 3D-printer and uses a single piece of ABS or PLA plastic threaded through the back. The standalone device allows the user to effectively draw in the air, making structures that stand as strong and rigid as anything constructed by the Makerbot , if slightly less finished in appearance.
